Expected Behavior

Audio works the same way as on a flashcart

Actual Behavior

MP3 files have crackling or produce noise in certain parts
Other files work fine or exhibit same bugs on flashcarts (AKA have issues not related to nds-bootstrap). Tested formats are MP3, OGG, WAV, FLAC and XM

Steps to reproduce

0. Get audio files in formats supported by Moonshell
1. Launch Moonshell (Direct Boot)
2. Play the files

nds-bootstrap.ini

Logs

Other notes

Default Moonshell file crashes for me but Direct Boot works - might be a separate issue.

MP3 files used for testing were in mainly 128kb (constant), 44100hz format

The session log recorded involved playing several files of different formats, including continuing MP3 playback at the start of the session.

Will you be available for future issues and/or replies?

Yes

I can confirm the same problem exists with NDS Bootstrap version 2.0.2 on New 3DS with MP3 files.

I use NDS Bootstrap with Twilight Menu, both installed on 3DS console and on an Ace3DS X flashcart. I notice the issue persists if I launch my slot-1 card via Twilight Menu, then launch Moonshell 2.10 on my flashcart. Audio crackles excessively.

A nice test track for comparing playback would be the Wii menu music, or day/night cycle from the weather channel Wii OST. Extra crackly when MS 2.10 is launched via bootstrap, and when booting flashcart via console-side Twilight Menu, then launching MS.

All the excess crackling disappears when I launch my flashcart directly from the 3DS home menu, then launch MS 2.10.

I have most of my MP3s encoded with 192kb/s constant bitrate, 44100hz.

Try changing the Sound/Mic frequency setting to 32khz in the nds-bootstrap page of TWLMenu++ Settings.

Try changing the Sound/Mic frequency setting to 32khz in the nds-bootstrap page of TWLMenu++ Settings.

Changed this both on console and flashcart installation of Twilight Menu. Still extra crackly.

Confirming this still occurs in nds-bootstrap 2.4.5 with no workaround working. Do we know any root cause yet? Thank you.
